What happens in photosynthesis?
|
Plants convert light enerfy into sugars and starches.
|
|
|
What are autotrophs?
|
Organisms that can use a source of energy (sunlight etc.) to produce food from simple, inorganic molecules in the enviroment.
|
|
|
Whare are heterotrophs?
|
Organisms that get energy from food they consume.
|
|
|
ATP (adenosine triphosphate) is...
|
...the most important energy-storing compound in a cell.
|
|
|
Light reactions:
|
in the light reactions, energy of sunlight is captured and used to make energy.
|
|
|
Dark reactions:
|
in the dark reactions, energy stored by the light reactions is made into glucose.
|
|
|
photosystems:
|
The photosynthetic membrane that are able to capture the energy of sunlight.
|
|
|
Dark reactions are also known as the:
|
Calvin cycle
|
|
|
In glycolysis, what happens?
|
a series of enzymes catalyze chemical reactions that change glucose into different molecules.
|
|
|
What happens in the aerobic process of respiration?
|
Respiration is the process that involves oxygen and breaks down food molecules to release energy.
aerobic = requires oxygen |
|
|
The first set of reactions in respiration are known as:
|
the Krebs cycle
|
|
|
Events of Krebs cycle:
|
*2 carbon atoms added
*2 carbon atoms removed *3 molecules of NAD+ converted to NADH *1 molecule of FAD converted to FADH2 *1 molecule of GDP converted to GTP |
|
|
photosynthesis and respiration are:
|
opposite processes:
photosynthesis deposits energy respiration withdraws energy |
|
|
Is fermentation aerobic or anaerobic?
|
anaerobic
(doesnt require oxygen) |
|
|
fermentation does what?
|
enables cells to carry out energy production without oxygen.
|
|
|
2 types of fermentation:
|
alcoholic fermentation
& lactic acid fermentation |
